Top Quality is true broadcast quality which is 60 fields per second, full overscan (752 pixels wide by 480 lines high).
Internally the Toaster works with D2 data so there is no D2/composite transcoding.
The Flyer uses NewTek's Video Toaster Adaptive Statiscal Coding (VTASC). VTASC relies on limiting the video signal (i.e. dropping to Beta SP quality) instead of lowering picture quality, as do JPEG, MPEG and WaveLet. The resulting output is broadcast video. Unlike other common compression schemes there is no visible pixelization. Using faster drives, lossless D2 quality can be acheived.
The audio is 8 bit sample at 14.3 MHz using state of the art A/D, D/A converters.
Flyer requires: Amiga 2000 or 4000, Video Toaster Card and Video Toaster System 4.1 software with 9MB of RAM minimum, 100MB free on hard drive. The following are the capabilities offered by various hard drive configurations:
One Fast SCSI II (video) drive: Cuts-only editing, no split edits or addtional audio tracks available, can record LightWave animations as video clips, any length up to the capacity of the drive.
One Fast SCSI II (video) drive, one SCSI (audio) drive: cuts-only editing with split-edit capability, two additional stereo pairs can be played from audio drive, can record LightWave animations.
Two Fast SCSI II (video) drives, one SCSI (audio) drive: Full A/B roll editing, with split-edits capability, and two additional stereo audio pairs can be played from the audio drive. Can record LightWave animations.
Input from video tapes must be time base corrected. Consult your dealer to configure a system suited to your needs. Some features require an Amiga with the AGA chip set and 2 MB of chip RAM. Specifications subject to change without notice.
